supremes causing - weird rear end noise-63 buick?

I got a new set of springs in, a new center bearing mount and u joint and my new supremes on.

I take it for a test ride down the street, and it sounds like I got hubcaps with rocks in them.

I jacked it up and noticed a little play with the wheels on. It looks like the lug nuts are not tightening down the wheel stud and the brake drum.

ie: when the wheels are on , I can move the drum an 1/8 of an inch clock wise or cc. The longer studs for these wheels look too long. Without the oblong washers it looks close but not close enough.

Can I Or should I put a washer behind the wheel between the lug nut and the drum? Any other suggestions? Maybe a blown bearing? thanks

 

Astro's are a cast center wheel?

Sounds like long studs or long mag wheel lugnuts.

Pull a wheel and insert a mag lugnut.
If it sticks out, it's bottoming on the brake drum/hub before it's pulling the wheel down tight.


If that's not it, measure the wheel thickness and the depth of the mag lugnut.
Bottoming the mag lugnut on top of the wheel stud happens now and then.
Same results as above, the wheel is not pulled down to where it should be.

 

no cast center- just a popped cap

any suggestions? like you said - not being pulled down enough would be my guess also. the longer studs are too long.

 

I believe thos wheels have a cast center. As in: the center of the wheel itself is about 3/4" to 1" thick. I think they need a mag wheel lug nut, right?

If I'm not mistaken, those mag wheel lug nuts come in different lengths. Just get a set with a shorter shank....know what I mean?

Call your wheel supplier. If you bought them used, call a place that sells them. They should be able to hook you up with the right lug nuts.

 

yes

yes

nope- I havent yet found anyone locally that could help. everyone has forgotten about the "old style mag wheels" everyone is deep in the mindset of dubs .

and i have only been able to find the 1/2'' x 20 thread (rh and lh) in the length I have, which is 0.80''

 

hmm...ok.

So if your lug nuts are bottoming out before the wheel tightens down all the way, then why not add an extra washer under the head of the lug nut.

Know what I mean?

That would make the shank shorter by 1/8" or however thick your washers are.


I don't know. I've never ran into this problem personally.
BTTT for ya at any rate!

 

Measure the wheel thickness at the lug hole.

If it's longer than the mag lugnuts you're in business.

If longer, you can cut some off the lugnut - a lathe preferred, but a hacksaw would do it.
You can also put a thicker washer under the lugnut's hex.

Do not put a washer between wheel and wheel mounting surface - IE: brake drum etc.

 

Also, I hate to say it, but try Auto Zone. They should have a bin in the back with all sorts of different type lug nuts in them. The packets out on the shelf will all be the general stuff.....ask the guy behind the counter to take you in the back and show you the real lug nuts.

Watch out though. That sort of thing can get out of hand if not worded correctly.

 

That is funny. I havent found anyone locally that sells left handed 1/2'' x 20 lug nuts, summit only has the ones that i currently have. From what I have gathered thay are to short. they bottom out on the wheel, not the drum. in fact they are probably are 0.20 '' to short.

 

Ok. Then disregard everything I was saying. I thought it was bottoming out on the drum.

I'm kinda lost.

Got pictures? That could help I think.

 

Buicks got left hand lug studs?

I thought ChryCo was the only one that did that.


Get some replacement lug studs from the Dorman bolt supply cabinet at a "real" parts house and replace the left handers.

Another way out is a right hand hub on the left side.

Since we're perhaps dealing with a ChryCo car, is there any chance the guide pin on ChryCo hubs is holding the wheel off the surface?

I cured that on my 51 Plymouth sedan with a hacksaw when I ran Ford wheels on it.

 

My buick has left hand lugs too.

 

After closer inspection. It appears that the wheel is fitting incorrectly.The hub(flanged) is sticking out approxiamatly 1/8'' and center of the wheel does not fit over this. With the cap on it sticks out even more. and with the washers on it makes the lug nut probably 1/4'' to short. But the real problem lies in the hub sticking out the additional 1/8'' . with a 1/4'' spacer between the wheel and the drum all would be fixed, but this doesnt sound right. Here is a sketch.

I might have to start a new thread ***led diffrently. thanks

 

are these real US supremes or the copys?

 

cragar's

 

sounds like you're on the right track with a 1/4 spacer and longer lug nuts.

 

on the buicks i've had, on one i turned down the flange on the rear axles on a lathe to fit supremes as a permanant fix, others i've just run a 1/4" spacer.

while you're at it, make sure your fronts are seated correctly too!

 

thank you all so much - spacers and lugs it will be.

 

Thought about swapping out the studs for right hand?

Might work, I wouldnt think that anyone would make a hub that was unidirectional... So I'm thinking ya should be able to pop some right hand threaded ones in.

Be more work, but the parts store probably has em...
